Choose the correct answer from the options given below:

(A), (C), (D) and (E) only

Fat-soluble vitamins are those that can dissolve in fats and oils. They are absorbed along with dietary fats and are stored in the body's fatty tissues and liver. Here's a brief explanation of each fat-soluble vitamin mentioned:

(A) Vitamin A (Retinol): Vitamin A is essential for vision, immune function, and cell growth. It is found in animal sources as retinol and in plant sources as provitamin A carotenoids, such as beta-carotene.

(C) Vitamin D (Calciferol): Vitamin D is crucial for maintaining healthy bones and teeth as it helps the body absorb calcium. It is often called the "sunshine vitamin" because the body can produce it when the skin is exposed to sunlight. It can also be obtained from dietary sources like fatty fish and fortified foods.

(D) Vitamin E (Tocopherol): Vitamin E is an antioxidant that helps protect cells from damage caused by free radicals. It also plays a role in immune function and skin health. Good sources of vitamin E include nuts, seeds, and vegetable oils.

(E) Vitamin K: Vitamin K is necessary for blood clotting and bone metabolism. It is found in leafy green vegetables, vegetable oils, and some fruits.

These four vitamins are soluble in fat, meaning they can be dissolved in fats and oils. They are absorbed along with dietary fats and can be stored in the body's fat tissues and liver for later use. In contrast, water-soluble vitamins, like the B vitamins and vitamin C, dissolve in water and are not stored in the body to the same extent as fat-soluble vitamins. So, the correct answer includes vitamins A, D, E, and K, making option 3 the correct choice.
